The skies need to turn bluer and the only way to do this is by introducing a hue of green in the aviation industry. Airplanes today tend to burn tremendous amounts of fuel, resulting in an increasing amount of air pollution. The only way to snip this problem at its roots is by developing aircraft that are energy-efficient and eco-friendly. Designer Oscar Viñals seems to have been thinking along the same lines and has lately introduced a concept airplane called the AWWA-QG Progress Eagle. Inspired by contemporary jets, the Progress Eagle integrates quantum mechanics to its advantage.With a seating capacity of 800 passengers, the Progress Eagle sports 3 decks and uses an electric superconductive engine. The concept airliner is a great way to transport a larger number of passengers in a more eco-friendly way, making the Progress Eagle the best way to take to the skies in the future!
